 This file sets the GPRs to explicit values prior to execution.
 This allows for example a function call's parameters, according
-to Power ISA [ABI](), to be set conveniently and quickly, but
+to Power ISA
+[ABI calling convention](https://git.libre-soc.org/?p=openpower-isa.git;a=blob;f=media/calling-conv;hb=HEAD),
+to be set conveniently and quickly, but
 more importantly without requiring execution of additional
 instructions.
 
+In this example below the parameters point to areas of memory
+that are loaded or dumped, containing the input and output areas
+of the function.  They match up with the other parameters to the
+example script
